Thanks, Deagol. So, reading the seller's spiel again, with information from the page you supplied a link to - we can say that this item once belonged to a friend of Tolkien's, but the item itself has no connection whatsoever with JRR.

Now, I got confused whilst reading this sales description. I often wonder, when seeing convoluted pieces of writing such as this, how folk manage who do not have English as a first language. To take a wildly different example - there are folk (native English speakers among them) who are convinced that Lewis and Lacon's 'Fall of Gondolin'' has approval from the Estate. Largely because of wooly descriptions such as we have here.
